They widely use modern technologies of wireless data transmission both in the production activities of most companies and for building computer networks for at-home use. New hardware solutions in the field of wireless data transmission allow you to create and wireless computer networks within the same building and distributed networks throughout the city. A wireless user who has a laptop or pocket PC equipped with a built-in wireless module is no longer connected to a wired local area network but can walk freely in rooms or move to a nearby building while remaining attached to the system. Roaming support allows users to maintain a permanent connection to the system, while within the wireless coverage area. Corporate employees who make regular business trips for business purposes consider wireless technologies as a necessary part of their business. Wireless computer networks are actively deployed in public places such as hotels, transport terminals, restaurants, cafes, giving Internet access to visitors. According to experts, the intensive development and widespread popularity of wireless data transmission technologies over the past few years were due precisely to this opportunity.
One can install wireless computer networks for temporary use in areas where there is no wired LAN or if network cabling is difficult. Installing and configuring wireless networks is easy. The wireless network is built based on base stations (Access Point). An access point is a kind of bridge that provides wireless access to stations equipped with wireless network cards between themselves and computers connected to the network through wires. The radius of coverage of one access point is about 100 m. At the same time, one point can simultaneously support several dozen active users and provides information transfer speed for the final subscriber up to 11 Mbps. With the help of access points, wireless workstations, laptops, handheld devices equipped with wireless communication modules are in a wireless computer network, the performance of which depends on the number of concurrent users. To improve the performance of the wireless system, one should install additional access
Compatibility of a wireless computer network with a wired infrastructure is not a problem at all since most wireless access systems comply with industry standards for connecting to Ethernet networks. Network operating systems support wireless nodes (like any other network nodes) using network device drivers. Compatibility of different wireless network systems is indeed a complex problem since there are many different technologies and manufacturers. Besides, the harmony of devices, one should consider using the same
Low cost, fast deployment, extensive functionality for the transfer of data traffic, IP-telephony, video – all this makes the wireless technology one of the most promising telecommunications areas.
